NOTES ON LONG ISLAND WELLS. 
I have not been able to obtain records of many of the wells on Long 
Island, and for the greater number I can give no further information 
than appears in the above table. In most cases well borers have not 
saved or recorded the materials penetrated, and we must depend largely 
on that sort of data for a determination of the underground geology. 
Some borings have been placed on exhibition in the museum of the 
Long Island Historical Society, which I examined with care, but the 
general absence of fossils and lack of distinctive materials preclude a 
determination of the age of the deeper seated beds. 
Brooklyn City Water Department. — I have not been able to secure 
extended information regarding the wells which furnish a large propor- 
tion of the water for the city of Brooklyn. Tbey are in " gangs" sunk 
at a number of pumping stations along the southern side of Long 
Island from Spring Creek to Freeport. Their aggregate capacity is 
stated to be about 22,000,000 gallons per day of twenty-four hours and 
the water is of most satisfactory quality. The wells are nearly all 
flowing, but they pump down to a few feet below the surface. It is 
stated that when the deeper wells were sunk at Jameco the flow from 
a 6-inch pipe was 500 gallons per minute and the water would rise to 11 
feet above the surface. In recent extended tests reported by Engineer 
I. M. De Yarona it was found that pumping 1,000,000 gallons per day
